The underworld is rising in Midian, Tennessee, a small town and burgeoning hotspot of demonic activity. When a string of savage and horrific murders committed by demons shocks the town, the unsuspecting Sheriff's Department scrambles to track down the culprit. Working outside the bounds of the law is Deputy Archibald "Arch" Stan and demon hunter Lafayette Hendricks. The two of them are keeping watch on Midian, trying to thin the demon population - a heavy task even when there isn't a rising body count to deal with. Their investigation leads them on a twisting path that sends them up against the forces of hell, has them at odds with their significant others and may even cost them their lives. Because a new demon has come to Midian, one that has a taste for death... ...and he may not leave the town standing when he's done.
